#
# runSPADE:  R wrapper script for SPADE tree construction
# Erin Simonds - esimonds@stanford.edu
# Version 2.6 - September 24, 2013
#
# Command line instructions:
#   1) Make sure the first line of this file is your Rscript path (found in the same directory as R)
#
#   2) Customize the parameters that are CAPITALIZED below 
#
#   3) In a command shell, navigate to the folder containing this script and the FCS file(s) to be analyzed
#
#   4) Make this script executable.  At the command line, run:
#   $ chmod +x runSPADE.R
#
#   5a) For normal use (not in a load sharing or compute cluster): At the command line, run:
#	$ ./runSPADE.R [-num_threads=X] [-file_to_process=Y]
#	where X is the number of threads you wish to use (default = 1)
#	Y is the name of the file to process (default = use file(s) specified in this script)
#		Note that parameters in brackets may be omitted.
#
#   5b) For Sun Gridengine: At the command line, run:
#	$ qsub -cwd -j y -b y -m e -M username@domain.ext [-pe threaded A] ./runSPADE.R [-num_threads=X] [-file_to_process=Y]
#	where username@domain.ext is your e-mail address to e-mail when the job is done,
#	A is the number of slots to reserve with Gridengine,
#	X is the number of threads to use in SPADE (usually the same as A) (default = 1).
#	Y is the name of the file to process (default = use file(s) specified in this script)
#		Note that parameters in brackets may be omitted.
#
#   5c) For Platform LSF: At the command line, run:
#	$ bsub [-n A -R "span[hosts=1]"] ./runSPADE.R [-num_threads=X] [-file_to_process=Y]
#	A is the number of slots to reserve with LSF,
#	X is the number of threads to use in SPADE (usually the same as A) (default = 1).
#	Y is the name of the file to process (default = use file(s) specified in this script)
#		Note that parameters in brackets may be omitted. (Note that the brackets surrounding "hosts=1" do not indicate an optional parameter.)
#
# Interactive instructions:
#   1) Customize the parameters that are CAPITALIZED below 
#   2) In an interactive R session, change the working directory to a folder containing this script and the FCS file to be analyzed
#   3) At the R command line, run: source("runSPADE.R")
